Convert EPSF to RAD

An EPSF, or Encapsulated PostScript File, is a graphics file format used primarily in the publishing and printing industries for embedding high-resolution images within other PostScript documents. Introduced by Adobe Systems in the late 1980s, EPSF files enable seamless integration of complex visual elements, maintaining quality and device independence. They encapsulate both vector and raster graphics, allowing detailed illustrations and photographs to be embedded without loss of resolution, facilitating professional-quality output across various platforms and devices.

The RAD file extension, associated with the Radiance software suite, stands for Radiance Scene Description. It is used to describe materials and geometry for lighting simulations and rendering programs. Developed by Greg Ward at Lawrence Berkeley National Laboratory, Radiance employs ray tracing and an octree data structure for accurate lighting calculations. RAD files are ASCII text files that must be compiled into an octree before rendering.
